IMPROVEMENT IN BEDSTEADS.

Specification forming part of Letters Patent No. 152,370, dated June 23,1874 application filed October 13, 1873.

To all whom it may concern:

Be it known that I, JAMES L. HAVEN, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Improvement in Bedsteads, of whichthe following is a specitication:

My intention is designed for the tenon or male part of a metallicfastening for bedsteads and other sepa able furniture; and relateswholly to the means for securing the same in the rail or other memberfrom which it is to project.

Figure 1 is a perspective view of the parts Fig. 2 is a section at theline 00 m. Fig. 3 shows my fastening in position in the rail end. Fig. 4is a section at the line 3 y. Fi 5 is a vertical section, showing amodification of my improvement.

A may represent a portion of a bedstead- B may represent a tenon head ofany customary or approved form. Customary neck or necks G O uniterearwardly in a wing or shank, D, to occupy a corresponding mortise-kerfor excavation, E, in the rail or other member from which it is toproject. A notch, (I, or hole (1, entirely across said shank, receives aglued wooden plug, F or F, whose thickness corresponds to the width ofthe eX- cavation. This plug serves both to secure the fastening and toreunite the walls of the excavation. The shank, when of the form shownin Fig. 1, maybe plugged after insertion; but

when of the other form shown must be plugged before insertion.

Although preferably segmental, as represented, and made to fit eachother, nevertheless the shank D or the mortise E mayhave any other formor contour in the vertical plane of the shank. The shank and plug ineither case are driven endwise into the mortise which is cut in thesolid end of the rail, and in the illustrations the mortise is adaptedto be formed at a single simple operation by arevolving cutter.

The segmental shape of the shank in its preferred form, and theperforation or recess therein, broadly considered, are known to be old,and are hereby disclaimed. These features of my present invention areshown, for instance, in J. Rodefers extended patent, dated April 10,1855, and reissued to James L. Haven 85 00., June 20, 1871, No. 4,432.

I claim as new and of my invention-- The combination of the rail A,having the mortise E formed therein, the recessed tenonshank D, and theglued wooden plug F, substantially as shown and described.

In testimony of which invention I hereunto set my hand.

JAMES L. HAVEN.
